By now, you're familiar with the cinnamon challenge. Maybe you know someone brave enough to ingest a spoonful of cinnamon on film. Or perhaps you were foolhardy enough to try it yourself. There's even a chance you heard about some of its health risks.
But you can still get your kicks without endangering your health. And heaven knows YouTube is the place to embarrass yourself -- er, experiment.
These 10 challenges replace cinnamon with an equal amount of hacking, gagging or worse. Among the videos you won't see listed here: the Taco Bell challenge, the Greek yogurt and root beer challenge or the condom challenge (we can't advocate suffocating yourself with a strip of latex).
We worked to compile 10 of the most extraordinary and demanding challenges, or at least the videos in which participants make the best faces. Check out the gallery above for a full rundown of Internet champions.
Did your favorite challenge make the list? If not, let us know in the comments.
Note: If you do try these challenges at home, please don't choke. Kthanksbye.
